Killer tornados not OK

I've never liked the abbreviation for Oklahoma.  Abbreviations should never spell words that could later be misconstrued as the actual word. 

Case in point:

Today's headline from the Daily Beast Twitter feed:

2 Killed in OK tornados ... At least 4 twisters hit southeastern region of state.

Yes, it only took me less than a second to realize the tornados were not receiving the Daily beast's seal of approval, but that was a rather appalling microsecond of confusion.
